A conronnrrolv or ILLINOIS FISH-TRAP, s'rrwornnn Application filed July 5,

This invention has reference to fish trap structures and it has for its principal objectto improve the body of such structures; to provide improved means to strengthen the selvage or marginal edges of the sections of to manufacture such structures at a ,consid- V erably reduced-cost than heretofore. This larged, the characterof the bodyof the fabric of the structure, the reinforcing means, manner of connecting adjoining selvage portions latter element isimportant whenit is considered that structures of this character are used, as a rule, only one season.

Fish traps of the character referred to are used particularly in the salmon-industry.

Other and further objects will more fully appear from the following description.

That the invention may be more fully understood, reference is had to the accompanyingdrawings, forming part ofthis descrip tion, illustrating a preferred embodiment of." the invention, in which j V j V a 1 Fig. l is a vertical elevation of my im- 1 proved fish trap structure, on a greatly re'-t-. duced scale, and showslin asomewhat con ventional manner andit might be said, di'a-. grammatically, several sections of: such a structure connected together and to pilings porting means; .7 v

-The'fabricof my invention is preferably of square meshandmade in sections prfeferably six feet wide and seventy-two to ninety feet long with meshes two byfour, inches; the two inch meshes disposed vertically and the four inch meshes disposed horizontally. While it is desirable to understand the width and length ofthe sections offabric constituting a "structure, and'to understand'something of the'size of the meshes,'I'do notdesire to implythatthesef are limitations as I realize fully variations may be necessary to meet conditions from time to time; Also, 'while.thestructureofFig. 1 is shownfsusture of Fig. '4 is sustained by a floating struclture and weights, these are not intended as limitations but'inerelyjillustrativelj The fabric is composed of"longitudin al wires and crosswires' 2, so -spacedflas to producethe size meshes; desired and I'prefer gauge and "weight and preferably ,;of the longitudinal selvage or marginal wires, which Iprefer shall beef a much heavier gauge and ;weight, as such-wires provide,"-noton'ly the gether jvi th the selvageor marginal-wires of ployed to holdthe structure in proper vertical merit of the water. Furthermore; I "prefer I that the wires 1 and-2 where they intersect shall be taph connected, as zit-"3, and the cross Wires 2 connected,at theirends," to the heavier A marginal or selvage wires 1 by beingwr ipped A fish trap structure would embody a plu-- 1 "rality of sections of fabric. connected together 1 "In theconstruction ofa trap; whatever may or 'c'oiled thereahou't, as at 4.,

tained by p'ilings and weights andthe struc-= l'ighter gauges of wires, as comparediwith'the reinforcing means-for the sections, but to-- position in the water andagainst the movethat 'the 'cross wires? and-the intermediate longitudinal wires 1 shall be] ofuiniform,

so and showing the reinforcing and weight-sup adjacently placed sections provide strength 'ening'ribsin the trap structure to'siistain thesame and additionally, to, provide the sustain ing means for the weights. which areie'mposition and the sections of fabric taut and straight, by means of weights 5.

A stringer 6, of heavy gauge material or a cable is provided for the attachment thereto of the longitudinal wires 1, preferably by carrying the ends of such wire s 1 thereover and then coiling or Wrapping the ends'of the wires 1 about-themselves, seeFig. 4. Also,

when the sections of fabric are assembled, the heavier marginal or selvage wires 1 of adolning sections are connected by preferably hog-rings 7, see Figs. 2- and 4.

The weights are attachedto and sustained from and by pairs of adjoining heavy marginal or selvage wires 1 of the adjacently Iii placed sections'of fabric, in the manner best seen in Fig. 2. Here it is shown that the sustaining means 8 of a weight 5 is threaded up between a pair ofmarginal or selvage wires 1, thru a .hog-ring 7 and having connection with a similar 7 superimposed hog-ring. While I have shown this weight connection with the marginal or selvage'wires, it is to be understood this mode of attachment may be modified, as occasion demands. It should be obvious, however, that by providing the heavy marginal or selvagewires, the fabric,

- as Well as the assembled structure, is reinforced at these points and that such reinforcing means provides amplesustaining means for the connection and support of the weights for holding'the fabric vertically taut and straight and that so held the marginal or selvage wires being connected by hogrings, bulging between the adjoining sections is prevented. p

The stringer 6, provides the means of attaching the structure, at its upper portion to the pilings, see Fig. 1,.and also the means for the attachment of the structure to a floating support, as for instance buoys, see Fig. 4.

Constructing the fabric of square meshes and tying the cross-wires where they'intersect by staples, will prevent travelling or enlargement of any breaks in the fabric in the event of cutting by loose pilingor from other causes.

What I claim is A fish trap structure, comprising'sections of wire fabric,-each section made from a plurality of longitudinal and cross wires joined at their intersections to produce square meshes, the marginal longitudinal Wires being sufiiciently heavy to provide, when the sections are o ned, reinforcing and strength- 1 e ling-ribs for the. said structure, =means adapted for connection with the lower ends of pairs of marginal wires of adjoining sections for weighting down the said sections and to hold the same taut, rings connecting marginal wires of adjoining sections, and a stringer support for the structure to which are connected the longitudinal wires of each section.
